Video Flashing in Premiere - Plays just fine in QuickTime Player

[WestView Digital]

I've recently upgraded Premire and MacOS (to Monterey) after upgrading to a MacStudio from an old MacPro (which couldn't run Monterey or the newest version of Premirere)

Now I'm having issues with footage from my older camera (Sony FS-5,  XAVC-Long).    Footage from my FX-9 doens't seem to have the same issue.   

The video has subtle single frame flashing.   Looks to be always on the same random frames.   Still flashes when exported.   Origional clip plays fine if I open it in QuickTime player.  I've tried relinking media and importing into new project.   Also tried the color space override since I've had issues with old SLOG footage being color-corrected "twice" when opening old SLOG projects.   But this footage wasn't shot in SLOG.  I've attached short sample.

Adobe support took control of my computer so it was a little hard to keep up but.... He had me trash all the files in the media cache folders but we did it using the finder, not the option in Premiere's Preferecne menu.

Then he downlaoded and ran Creative Cloud Cleaner  (https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html)

There was some force quitting of background apps in the Activity Montitor but that looks to be outlined in the link above.

The CC Cleaner *I think* removed Premiere because then he had me download the stand-alone installer for premiere and re-installed it. 

Again, he did most of the work and I just typed in admin passwords when promtped.
